04 KJ with stock ignition and induction showing P0174 and P0175 repeatedly (and lost about 4 mpg). Need some opinions. Replace both bank 2 O2 sensors? Upstream only? Any other ideas?

Thanks, Russ

Cured it. Terrible access to O2 sensors. Not impressed with that bit of engineering. Put new NTK's in; seem to be identical to factory parts. Thanks for the advice.
